Thanks Inframan, Ann, Bee1000, Vikas and Viktor. Viktor, there are indeed some regions within the branch where the hue is purple (around 330 in PS) instead of red to orange but apart from a few regions the color of the branch looks like this in reality, at least on my non-calibrated monitor.

Nice picture. However, I think the color is off. The branch, which I would expect to be brown, is instead purple. Decreasing the blue channel seems to correct it without detracting from the lizard or background. -- Victor
